VEHICLE-SPRING.

c SPECIFICATION forming part of Letters Patent No. 236,281, datedJanuary 4, 1881.

Application filed August 4, 1880. (No model.)

To all whom it may concern:

Be it known that I, SEYMOUR VAN Nos- TRAND, of Stormville, in the countyof D utchess and State of New York, have invented a new and ImprovedVehicle-Spring, of which the following is a specification.

The object of this invention is to provide an adjustable vehicle-springof superior elasticity and strength,wh0se elasticity can readily beincreased or diminished at will.

Figure 1 is a plan of the spring attached to the side bars of a wagon.Fig. 2 is atransverse section on line as m, Fig. 1. Fig. 3 is anenlarged side elevation ofa clip holding the end of a transverse springto a side spring of the Vehicle-spring. Fig. etis an enlarged endelevation of the same. Fig. 5 is an enlarged side elevation of a'clipand coupling securing the end of a side spring to a side bar ofa wagon.Fig. 6 is an enlarged end elevation of the same. Fig. 7 is an enlargedplan of the coupling.

Similar letters of reference indicate corresponding parts.

In the drawings, A A represent the side bars of a vehicle, and B B theconnected'end bars thereof.

. O is the spring, the ends 70 la of whose side springs, O O, arerigidly secured on the under side of the side bars, A A, by means of theclips and couplings D E.

The clips D straddle the sidebars, AA, and have then-ends entered intothe holes a a of the couplings E E, and the couplings E E are secured onsaid clips D l) by the nuts I) b, that are screwed on the ends of saidclips D D.

The ends ofthe side springs, 0' O, are entered between the dependinglugs 01 d of the couplings E, and are there firmly held on the pins orbolts 0 0, that pass through said lugs 01 01, parallel with the sidebars, AA, and through the end eyes, ff, of the said springs C O.

The transverse or cross springs, G G, of the spring 0 cross from one tothe other of the side springs, O O, beneath the same, forming theH-shaped spring 0, and have their ends connected to the said springs G Oby the clips F F, that straddle said springs O U, and have their endsentered through the said springs G G and secured by nuts 9 g. Thisspring 0 offers not only an elastic supportto the vehicle-body that isdesigned to be placed upon the cross-springs G G, but also a torsionalor twisting resistance thereto, because of the downward-inclined curveof the ends of the side springs, O G. The springs G G are connected withthe side springs,C 0, in such a manner thatthe former may be movednearerto each other than herein shown, to increase the elasticity of thespring 0, by'bringing the bearing-point of the vehicle-body nearer thecenter thereof; or said springs G G may be moved apart to increase thestiffness of said spring 0.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

The H-shaped spring 0, consisting of the sides 0 O and cross-pieces G G,the former having bent ends k, downwardly inclined, to adapt the springto be applied, as shown and described.
